Problems solved by technology

[0004] However, the module in the light leakage area under the screen may reflect light to the top of the display, which will cause appearance problems; on the other hand, the light leaking from the light leakage area that is not related to fingerprint recognition will also affect the efficiency of fingerprint recognition
Due to the existence of the above-mentioned problems, the performance of fingerprint recognition under the screen is affected.

Abstract

The invention provides a fingerprint identification device and electronic equipment. The fingerprint identification device is applied to the electronic equipment with a display screen, is used for being arranged below the display screen, and comprises a micro-lens array; a small hole array which is arranged below the micro lens array; an optical fingerprint sensor array which is arranged below thesmall hole array and is used for receiving an optical signal which is converged to the small hole array through the micro lens array and passes through the small hole array; and a first 1 / 4 wave plate and a first linear polarizer which are disposed in an optical path from the display screen to the optical sensor array, wherein the first 1 / 4 wave plate is disposed above the first linear polarizer.According to the fingerprint identification device and the electronic equipment, through the first 1 / 4 wave plate and the first linear polarizer arranged on the first 1 / 4 wave plate, the performanceof fingerprint identification under a screen can be improved.

Description

technical field [0001] The embodiment of the present application relates to the field of electronics, and more specifically, to a fingerprint identification device and electronic equipment. Background technique [0002] With the rapid development of the mobile phone industry, the practical application of fingerprint recognition technology under the screen has become the demand of the public. [0003] The under-screen fingerprint identification technology is to install the fingerprint identification module under the display screen, and set a light leakage area under the display screen. The fingerprint identification module realizes the under-screen fingerprint identification by detecting the light carrying finger information transmitted from the light leakage area. [0004] However, the module in the light leakage area under the screen may reflect light to the top of the display, causing appearance problems; on the other hand, the light leaking from the light leakage area tha...
